Problems solved by technology

Therefore, the length of time the 3D glasses are turned on will affect the 3D display effect
However, when the scaler in the display device reduces the high-resolution source image to the low-resolution panel, its blank area will also be relatively reduced, so that the time for the 3D glasses to be turned on is also shortened, which is not conducive to the development of 3D display.

Embodiment Construction

[0025] Figure 2A It is a block diagram of an embodiment of the display control device of the present invention, wherein the display control device 20 includes a data processing unit 21 and a timing generation unit 22 . The data processing unit 21 receives an image frame and temporarily stores it in a buffer. The frame includes a valid data area and an invalid data area, and the valid data area is larger than a visible area of ​​a display panel 23 (ie, the area actually seen by the user). The valid data area may be a data enable (DE) area, and the invalid data area may be a blanking area. The timing generating unit 22 generates an output timing signal and sends it to the display panel 23 , so that a part of the valid data area (hereinafter referred to as the first partial area) corresponds to the visible area of ​​the display panel 23 . Therefore, when the data processing unit 21 outputs the frame to the display panel 23 for display, the display panel 23 can display the firs...

Abstract

The invention relates to a display control device and a method, wherein the image zooming time can be reduced, the image quality can be maintained, and the starting time of 3D glasses can be prolonged. The display control device comprises a data processing unit and a time sequence generation unit. The data processing unit is used to provide a frame which comprises an effective data area which is greater than a visible area of a display panel. The time sequence generation unit generates an output time sequence signal corresponding to a relative position of the effective data area according to the visible area, so that the part of area corresponds to the visible area of the display panel. The display panel displays a part of the area of the effective data area according to the output time sequence signal.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display control device and method capable of reducing the number of zooming images. Background technique [0002] In the field of display technology, scalers are widely used in display devices such as televisions and monitors, which can properly scale image content with different resolutions provided by image sources to completely display on the display device. As the content resolution of image sources is getting higher and higher, when encountering a display panel with a lower resolution, it is necessary to reduce the resolution of the image content, that is, shrink the screen to match the low-resolution panel, but this will May affect the clarity of content, especially content with high detail or small text, which will be less clear when zoomed out. [0003] Furthermore, in today's multi-media development, besides the personal computer (PC), the image source of the...
